iMX8 PLUS MIPI raw8

Hi
Our iMX8 PLUS platform
Our task is to get an image in RAW8 format (10, 12)
AR0521 sensor (4 lines MIPI)
I managed to integrate the driver for the sensor
And get a crooked image, the image is as if divided into 4 parts, the first two squares display the image of the image, the other two are just black.

The questions are as follows:
1) What changes need to be made to the MIPI (CSI) driver to get an image in RAW8 (10, 12)?
2) There is data on the MIPI bus, but there is no CLK, what could be the reason?

Any help would be helpful, thanks

Hi Russel

 

In case of using 5.10.x version of BSP, recommended to try applying the attached BSP patch, verified with OV5640 sensor.

 

Best regards
